(Atrioventricular Block by ECG Finding, NCI Thesaurus)

A tachycardia arising in the conduction tissues surrounding the atrioventricular node.

(Junctional Tachycardia by ECG Finding, NLM, Medical Subject Headings)

It results from an increased automaticity in the atrioventricular node and His bundle.

(Congenital Bundle of His Tachycardia, NCI Thesaurus)

A bundle of specialized heart muscle fibers that conducts impulses from the atrioventricular node to the ventricles.

(Atrioventricular Bundle, NCI Thesaurus)

An electrocardiographic finding of an arrhythmia originating from within the atrioventricular node.

(Nodal Arrhythmia by ECG Finding, NCI Thesaurus)

A multicystic tumor arising in the inferior interatrial septum in the region of the atrioventricular node.

(Cystic Tumor of Atrioventricular Node, NCI Thesaurus)

This agent also acts directly on the atrioventricular node to suppress conduction, thereby slowing conduction velocity.

(Digoxin, NCI Thesaurus)

Glycopyrrolate binds to peripheral muscarinic receptors and inhibits cholinergic transmission present in the autonomic effector cells of smooth muscle, cardiac muscle, the sinoatrial node, the atrioventricular node, exocrine glands, and in the autonomic ganglia.
